In distributed computing systems, the rationality of computational agents working cooperatively is significantly different from the agents working independently. Cooperation between intelligent agents requires the high level reasoning and complex interactions for successful operations. The required reasoning process includes knowledge representation and sharing as well as the ability to understand the context of a situation. The reasoning process heavily influences on the planning of deciding what actions need to be taken. Interactions between agents allow them to catch up other’s intentions in order to avoid any conflicts from their actions as well as their intention toward the common goal. Goal deliberation and planning is the process that deals with those requirements. This talk investigates the problem of goal deliberation and planning to enable such cooperation between goal-oriented intelligent agents, working as a team.
